Have the same problem once I upgraded to
NextGEN gallery 1.9.3
able to add new galleries but CANNOT UPLOAD any images into any gallery.
the image gets loaded "100%" but then NextGen Gallery does not recognize it's been added to the folder/gallery and returns a "0 picture(s) successfully added"
I can see the images in the folder on my server but not in NextGen, have tried
-"scanning for new images" button.
-uploading the images in a different way (ftp / zip upload etc)
- turning off all other plugins
- a different theme
- changing folder permissions
but none of these seems to work - anyone managed to solve this yet?
